Well, I loved it so much that I had to run the child to the library as soon as it was done on the excuse of returning her library books, but really, so I could check out the next one.
Bartimaeus is fabulously snarky, but this one really takes the time to explore how this alternate world England works. In short: the magicians have made a mess of things. Fortunately, there is a perfectly good character interested in fixing all this. I dearly love how Kitty doesn't even pretend that she's not going to keep right on at her chosen tasks.
Great stuff, including the lesser characters, both good and evil.
